I am was looking at the details of a Allen Bradley plc output card. The rack is a 1756 Allen Bradley, the card is OB32 which
means its a discrete output. I was reading the I/O module specifications and I was wondering why this card at 5v has a current draw of 300mA= .3 Amps and at 24 v this card has a current draw of 2mA= .002 Amps. Shouldn't it be the opposite, you increase you voltage shouldn't the current go up instead of down?
